Thinking of trading my yz 125 for an 05 kx250f ..
Can anyone who owns one or has owned one give me their opinions on the bike please?
I would use it mostly for trails with a yearly trip to the track.
Any advise would be great..
Also lets see your 05 250f.

just my thought, keep your 125. i have heard of the 04-05 having problems but im not 100% on what the problems were.

Thats funny I came off a yz 125 to an 05 kx250f. My 05 is great it has a 269bbk and talk about power the thing is crazy. The problem with 05's are that there tired. To make it worth while make sure it has every nut, bolt, and cover on it. If it has never been rebuilt expect to foot a huge bill for a motor rebuild. Typical problems with 05's are just overheating. Yesterday was the first time mine overheated, but i was going very slow trying to make a new trail in some woods so the bike had pretty much no air flow for probably 10-15 min. Not too bad in my opinion.

My yz is an 06
The 250f is all stock very clean looking and has had the valves and everything checked out.
Don't know about a rebuild though.
Here is the description of the bike by owner....



2005 Kawasaki kx250f. It is pretty much all stock and is always kept to stock specifications, except the suspension was set for a 135lb rider, but can be adjusted very easily. It does have an asv brake lever and graphics to cover all the plastics. I recently got custom number plate graphics to protect the plastics. It is a very able bike and has a very strong motor, which most Kawasaki four strokes are known for. It is garage kept and always meticulously maintained. It just had a fresh oil filter, air filter, and top grade castrol synthetic race oil put in it, I still have about a bottle left which I will gladly give you. All of that is completely fresh with no rides on it, and the air filter is well oiled. I have never crashed it, or it has never been in any bad accidents, I have only laid it over in a soft sand corner once at three palms as I'm not that experienced with big bikes. It has never been raced, I've only took it out to practice about 3 or 4 times. It has had around 6 hours of ride time since the whole engine and valves have been checked and adjusted. The tires have plenty of tread left on them. I am looking for a 125 because I am a smaller rider and need something just a bit lighter and I'm more familiar with 2 strokes.

And here is the pic...


Is this a good choice for a woods bike?

So the bike has never been raced..... Lets see custom number graphics, asv levers, tuned suspension, trick bike stand...... From what I can see on  that side it is all stock. What would concern me is that he said he has adjusted the valves. Depending on how frequently he had to adjust them they could be on there way out.

Ok contacted him back and asked if it had ever been rebiult.
He said it had been rebiult by our local Kawi dealer and has since had 6 hours put on it.
He said he had it in there this spring and had everything check out since he had not ran it for the winter.
He purchased it to race it but he claims that being 135 pounds ..he is having a hard time with the bikes weight.
Hence it not being raced yet.
He raced last year on a 85
I Cannot comment on the previous owner.
My concern is i know of the dealer but have never delt with them enough to take their word on the bikes condition.

Hard to tell weather there reputable or not. You could call them and feel them out on doing a rebuild on that year bike and see if they sound like they know what there talking about. I also see he keeps saying everything was "checked out", but never states that they replaced anything. Rebuilt could be as simple as tearing it down and putting a new gasket set on. I'm not trying to scare you away from this, but you want to be very cautious. 4T are very expensive to rebuild. If anything ask for the receipts.

This is exactly why im being cautious.
The current owner has not rebiult anything.
The previous owner had it rebiult at the same dealer.
Right now my yz can sit for a month all i gotta do is start it up and go.
I do keep up extremely on maintence but i dont have an extra 1000 sitting around to rebiuld a 4t.

IMO if your going to be mainly riding woods stay away from the older kawi's and all Suzuki four strokes, the older Kawasaki 250f's are very prone to overheating. If i were you i'd stick with your 125 you have now, awesome bike for the woods and is dirt cheap to fix if anything does ever go wrong! My last bike was a four stroke and they are not nearly as fun to ride as a two stroke, especially in the woods.

KEEP THE 2 STROKE

I disagree with this my 250f is far more fun in the woods than the 125. A ton more bottom end with way more top end than a 125. Its all riding preference i guess. As i said before just cruzing in first gear is enough air flow to keep the 05 from overheating, given the cooling system is in tip top shape. A high pressure cap also helps and isn't that expensive. Aside from that they are expensive to rebuild and if the funds aren't available then that's a valid reason to stay away from any 4t.

I was ~125 pounds when I first got my 05, never had issues handling it. If you keep up with the maintenance (clean air filter and oil changes, etc), she'll serve you well.

Don't ever remember overheating it, however I do ride MX and not trails. Plus I use Engine Ice coolant.

If it does need a new top end; Motosport has a Wiseco piston kit for $210, Dave from MX Time will cut your valve seats and put in new SS valves for $425.

Oh and don't forget to get a new cam chain ($40) regardless, I'm willing to bet it hasn't been replaced.

BTW how much is your YZ worth/is he asking for the 05?


My 05

I have an 05 kx250f myself. I have never had any problems with it. i have raced mx and a 100 mile enduro on it. everything is stock on it besides a high compression JE piston in it, fmf powercore 4 exhaust and the obvious little things (jetting, pro taper bars, renthal sprockets, D.I.D chain, Hand guards ect) and still no over heating problems. even in enduro. always runs good. i love it. just keep up on maintence and even a rebuild wil be cheap. i had my piston put in by a local mechanic and he adjusted the valves with the piston and gskets and it cost me $535..

Pay a litle more for an 06 ..06-12 are great.

I got my 05 kx250f in arkansas for 1500,an my buddy got an 08 for 2500 both in great condition so I figure u prolly overpayed a tad bit

Decided to keep the 144 for now...
Unless i can grab an 06.

i have an 04 kx250f , its a good bike , you just gotta watch it on the really hot days for the common overheating. but other then that i honestly wouldnt worry about it , its no worse than any other thumper , plus i jumped off from my yz250 to the 250f and i liked it , thats when the saying smooth is fast or lower is faster comes to play.but anyways id do the trade

o4 -05 had all kinds of issues with overheating especially 2004 1st gen . Id go 2006 and newer or maybe a 250 2 stroke.
